To all? whmn it may concern):

e it known that we, FORTUNATUS GAL-' nirnrrn Knrrioee', a citizen of the United ,and exhaust strokes of the piston.

ject of the King of Great Britain, residing at Tacoma, in the county of Pierce and State of Washin ton, have invented certain new and useful mprovements 1n Lubricators, of wluch the following is a specification.

.Our invention has relation to automatic lubricators for air-pump air-cylinders "and it consists in'the novel constructions, combinations, and arrangements of parts hereinafter described and claimed, whereby a measured and regularly-intermittent supply of oil is fed to ,the air-cylinder by the action of suitable valves operated and controlled by the charge Referring to the accompanying drawing, the figure illustrated is a sectional view of the assembled lubricator, consisting of oil cup and cap and valve-body fitted with two ballvalves, valve-chambers, and intermediate passages.

In the drawing, A designates the oil-cu and Ba valve-body. The latter consists of a thimble threaded on both ends and formed with a central narrow passage H, connecting two larger recesses in which are fitted the stems of headed plugs F F, having central channels or passages G G for the oil. Between the inner ends of the plug and inner ends of the recesses chambers E and E are provided, and in each is a ball-valve D D, respectively, having room for slight vertical movement. The oil is worked through from the oil cup to the air-cylinder through pas-.

G into chamber E, past ball-valve D, through passage H, into chamber E, past ball-valve D, through passage G, into pipeelbow that leads to air-cylinder. The ballvalves D and D are so arranged that at each charge-stroke of the air-piston they are un seated from valve-seats K and J and are seated against valve-seats J and K, and at each exhaust-stroke they are reseated onto valve-seats K and J, the lift of the ballvalvvs l) and .l) being sulllcient to allow of a small quantity or oil passing each valve at each stroke or the piston. For instance, the valves D and D bein in the position of repose the/valve-seats l and J are closed and no oilcan pass; but valve-seat J being open the oil from oil-cup A is able to rundown throu hpassage G and fill chamber E. The %st 0 arge-stroke unseats ball-valves D and 5 from valve-seats K and J, seating them against J and K, thereby allowing the oil in chamber E to pass valve-seat K into passage H, Where it is held by ball-valve D on valveseat K. ball-valves D and D unto valve-seats K and J, thereby allowingthe oil in passage H to pass valve-seat K and fill chamber E, and the oil in'oil-cup A is again allowed to pass valve-seat J and refill chamber At the next charge-stroke the ball-valves D and D,

being again unseated from valve-seats K and J and being seated against valve-seats J and K, the oil in chamber E is allowed: to pass valve-seat J throu h passage G to,the air-, cylinder, and the oil in chamber E is allowed to pass valve-seat K and refill passage H, and so on with each charge and exhaust stroke of the air-piston the passages and chambers are emptied and refilled, and a small quantity of oil is sucked down into the air-cylinder.

What we claim as new, anddesireto secure by Letters Patent, is

In a lubricator for air-cylinderg the combination with the oil-cup, and the valve bod. or thimble havin a centralunobstructed 0i passage, and Va ve-chambers at the outer ends thereof, of ball-valves, arranged in said chambers and adapted to open and close ports to produce an intermittent'fiow of oil to the air-cylinder, each of said balls operating independently of the other and depending upon, and wholly operated by the exhaust and charge strokes of the cylinder.
